MATLAB: Format of an output of a function

MATLAB

Suppose A is 100*1 categorical and B is 100*1 categorical . As I run ismember(A,B), output is like

ans = 100*1 logical array
   1
   1
   1
   1
   1
   1
   1
    .
    .
    .

Thus I cannot see the output unless I auto-scroll that is not convenient. Is there any other way to display the output? For example, is it possible to have an output that does not require auto-scroll in the horizontal format such as

    ans = 1 1 1 1 1 1 1 1 1 (100 of 1s)

ismember(A,B).'

you would have received a row vector if A was a row vector

ismember(A(:).',B)

Use the logical negation symbol

~ismember(A,B)

or the functional form:

not(ismember(A,B))

MATLAB: How to combine multiple output from a function into 1

You can only do this if you know how many outputs you are expecting. That is because MATLAB only populates the outputs you request. For example, if a function produces 3 outputs, and you only ask for 1, then MATLAB will only populate 1 output. You need some way to tell MATLAB how many outputs you are interested in, which you can only do if you know how many outputs you are expecting.

If you know how many outputs you are anticipating, you can do something like this:

numOutputs = 3;
outputs = cell(1, numOutputs);
[outputs{:}] = ndgrid(-1:0, -1:0, -1:0);

If you are not sure how many outputs to expect, you may be able to use nargout (by providing a function handle as input to nargout), but that will only work with functions that produce a fixed number of outputs (unlike ndgrid, which produces a different number of outputs depending on the number of inputs.
